LOOM-HARNESS.

Sp'ecification of Letters Patent.

Patented Apr. 21, 1914:.

To all whom it may conce'm' Be it known that T, JACOB KALUFMANN, a citizen of the United States, residng .at Philadelphia, in coun ty :of Philadelphia and State of Pennsylvania, have inven'ted certain new and useful Improvements in Loom-Harness, of which the following is a specification.

My invention relates to loom harness and it has more particular relation to the' means for attaching the jack cords or strapsor other actuating means to the heddle frames.

The principal object of my invention is to provide a simple and eflicient device whereby thecords or straps for actuating the heddle frames maybe quickly and easily attached thereto, and which device is so constructed and 'arranged as not to cut or chafe the loop of the cord or strap.

My invention also contemplatesmeans for attaching the cord or strap whereby the same will not pull out froni the top and bottom bars of the heddle frames as frequently occurs where the ordinary screw hooks or eyes are used for this purpose.

The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure 1 is a front elevation of a heddle frame and its actuating jack cord with the device of my present invention shown inconnection therewith; Fig. 2 is a transverse section enlarged of the' upper bar of the heddle frame shown in Fig. 1 with one of the con- Iecting devices mounted thereon, the section being taken on the line 2-2 of Fig. 1; Fig. 3 is a front elevation of one of the connecting devices detached; Fig. 1 is a plan View of one of the connecting devices opened or flattened out to illustrate more clearly certain'features of my present invention; Fig. 5 is an enlarged sectional View of the upper end of one of the connecting devices taken approximately on the line 5-5 of Fig. 3.

Referring to the drawings, in the particular emhodiments of my invention therein shown, 8 is the heddle frame of any of the usual types, but which as shown may consist of the top and bottom bars 9 connected by the side bars. 10, which in turn support the heddle rods 11 upon which theheddles 12 are mounted. The top and bottom bars 9 are usually made of fiat lumber having frame bars 9 as clearly shown in Fig. 2 of the drawings, and from the outer edge of said bar 9 the two ends of the strip lconverge as at 16 and then eXtend in contiguous relationship as clearly shown in said Fig. 2. The contguous ends 17 of the strip 1 1 are each provided with a central slot 18. In the form shown in the drawings the slot continues in inclined direction to the side margin of said strip. It should be noted that the inclined portions 19 of the slots. 18 of each of the respective ends extend to the opposite sides of the strip 1 1 for a purpose to be presently explained. A portion of the niet-al from the slot 18 is bent outwardly and curled back as at 20 to the outer surface of the strip so as to provide rounded bearings 21 for the loop of the jack cord 13, which construction is clearly shown in Fig. 5 of the drawings.

It will be seen that there is a simple and efi'icient device the jack 'cord or strap to the which will not pull out or become detached notwithstanding the rough usage to which devices of this character are subjected, and that on account of the bent overlip 20 there will be provided rounded bearngs 21 at the outer end of the 'slot 18 which will prevent chafing or cutting of the jack cord or strap. Furthermore, in the forms shown the jack cord may be quickly and easily attached without untying the loop by merely springing apart the contiguous ends 17 of the fastening device 14 and passing the loop through the inclined portion 19 of the slot, first on the one side and then on the other, after which, when the strain is on the structure, the ends 17 will be held in close relationship by the loop of the jack cord, and the inclined open end 19 of the slot 18 of each end portion 17 will be closed by the lapping over of the soiled portion of the other conti'guous end portion 17 as clearly shown in Fig. 3 of the drawings.

Having thus described the nature and characteristic features of my invention what thus provided for attaching heddle frame slot in the other end of the strip, and the metal from said slots being curled over on the outer faces of the ends of the strip to thereby provide roundedbearing portons at the ends of the Slots.

In testimony whereof, I have hereunto signed my name in the presence of two witnesses.
